  • Page 5: Application

    1. APPLICATION The ND10 meter is a digital programmable panel meter destined for the measurement of the 3-phase, 4-wire power network parameters in balanced and unbalanced systems. It is also capable of displaying measured quantities and their simultaneous digital transmission. The meter is also capable of controlling and optimization of the power electronic devices, systems, and industrial installations.
